The equation is investigated for generalized symmetries using a recently proposed compatibility method. Some more general symmetries are obtained and group invariant solutions are also constructed for these symmetries. Besides this, the equation is also investigated for nontrivial local conservation laws UR - https://cmde.tabrizu.ac.ir/article_10323.html L1 - https://cmde.tabrizu.ac.ir/article_10323_cc57fc758759c3da3059edcd72c90cfc.pdf ER -
